(config)#
qos scheduling hybrid-6
<
txq0-weight

The following example configures hybrid-6 scheduling. The
show qos scheduling
command
displays the scheduling configuration on all ports.
device-name
(config)#
qos scheduling hybrid-6 10 15
% Actual proportions may differ due to limited granularity
device-name
(config)#
end
device-name
